    Default Zimbra Hardware performance and upgradation

    Hi

    I entered successfully into 2nd month of using Zimbra Network edition 4.0.1 . As an admin I have a question regarding Zimbra performance. Many of my new users are complaining on Zimbra's performance especially while using the webbrowser.
    Following is the ouput for df -h

    [zimbra@testl ~]$ df -h
    Filesystem Size Used Avail Use% Mounted on
    /dev/mapper/VolGroup00-LogVol00
    74G 41G 29G 59% /
    /dev/hda1 99M 12M 82M 13% /boot
    none 506M 0 506M 0% /dev/shm
    /dev/shm 150M 0 150M 0% /opt/zimbra/amavisd-new-2.3.3/tmp
    /dev/shm 150M 188K 150M 1% /opt/zimbra/amavisd-new-2.4.1/tmp

    The Zimbra server's RAM is 1GB. As you can see that 59% of the space got used, I am afraid to add users any more. I would like to get a suggestion on increasing Zimbra performance, hardware performance and the disk size. Are there any specials steps or rules to follow in doing so?

    Your memory is at the bottom of the required specification and you don't say what processor you've got. Lots more memory and a seperate raid array for the zimbra files would be my suggestion.

    I got P 4 processor. I will upgrade my RAM soon. If I upgrade my Hard Disk, is there any configuration to do in Zimbra to increase its volume?

    If you mean just replacing your current hd with another one then, no, there would be nothing to do. You could add another drive and move /opt/zimbra to that and add a symlink to the new location. If really depends on how many users and how important your mail is, a raid array would be the best for performance (raid10, I think) and safety for the zimbra files with mirrored drives for the operating system.

    What do you mean by "move /opt/zimbra to that and add a symlink to the new location"?

    Does it mean that I need to just cut and paste the /opt/zimbra to the new drive ? If so will it work then?

    How do I add a symlink to the new location?

    Are your users using ie6 or FF?

    IE6 has some bad speed issues, and horrible memory management. IE7 is a little better, but still not as good as FF.

    For more details, see the latest blog entry under "COMMUNITY".

    How many users?

    I have 1 GIG and 150 users, and speed is good here *with FF
